I use multipurpose (often mixed with some vermiculite and a bit of
sand/grit) for herbs. I agree that it it can dry out or at least that
it's trickier to resoak after it has dried out. But like the OP I have
it around so it's easier and cheaper.
The legginess is interesting. Basil certainly can tend to get leggy but
I thought that was the nature of the beast. Parsley on the other hand
doesn't in my experience get leggy even when grown in the shade which it
seems to quite like.

I find multipurpose okay for germination and first set of leaves then
pot on into better stuff. I find the multipurpose is looser than the JI
so you can get the seedlings out easier.
Mind you my basil gets leggy so perhaps I might try a change.
